2, the driver must resolutely obey the fire on the fire scene commander's command, wit the flexibility to perform the commander's command, to ensure the smooth implementation of the entire fire fighting. In the event of an irreversible change in the fire and a direct threat to the safety of the fire truck , the vehicle can be transferred to a safer place and continue to be put into combat, and the vehicle parking position can be promptly reported.  Second, fire vehicles into the fire a few questions when put into fire fighting and rescue, in operation should be noted.  　　 1, into the fire after the fire vehicle, the vehicle should be parked in accordance with a position designated fire commanders. The parking posture of the vehicle can meet the needs of attacking and retreating the fire field, and it must be ensured that the dangerous position can be withdrawn at any time. The engine of the vehicle must remain in operation. It must not be turned off blindly and the fighter should be delayed. When the fire truck starts to supply water, the water pressure should be gradually increased to avoid the casualties of the combatants caused by the reaction force of the water gun or the explosion of the hose, which will affect the smooth development of the fire fighting and rescue work.  　　 2 , in the process of access to water, it should pay attention to whether the fire hydrant water pressure can meet the needs of fire engines . When accessing natural water sources, attention should be paid to the water depth of the ponds and ponds, silt, etc. to prevent excessive shallow water depths and the intake of intake pipes from being affected by silt and causing water supply interruptions in the fire site.  　　 3. When the water source is beyond the fire station 's direct water supply capacity, the water supply for the fire field shall be adopted by the fire truck relay water supply method. The driver of the water supply vehicle should pay attention to the overflow of the overflow pipe of the water truck and maintain the proper water supply. When the rear vehicle cannot observe the overflow condition of the preceding vehicle, the driver of the preceding vehicle can open the manhole in the upper part of the tank of the vehicle to prevent the tank rising phenomenon caused by the excessive supply of water. In the process of water supply, the receiving vehicle should choose a hard surface for parking. When it is impossible to park a hard surface, necessary measures should be taken to prevent the vehicle from falling into the quagmire due to overflow. Water supply, should try to use the same type of direct coupling relay in fire vehicles, must be coordinated between the various vehicles, to prevent the improper operation of the water supply is interrupted. When the direct water supply pressure is high, care should be taken to maintain proper water pressure to prevent injury to the combatants.  Third, the proper use of foam fire engines in the fire field is the basis for extinguishing petrochemical fires.  　　 Foam fire engines are the necessary equipment for fighting fires in oil, chemicals, factories and mines, and port cargo yards. Because it also has the performance of a tank fire truck , proper use of a foam fire engine is a matter worthy of attention for every fire commander. Due to the special performance of foam fire trucks , it is determined that most of the fires faced by such fire engines are petrochemicals and other dangerous fire sites. Such fires have the characteristics of high burning speed, many changes in the fire conditions, high probability of explosive combustion, and large threats to fire engines and combat personnel. Therefore, in order for the foam fire truck to reach a favorable position on the fire, it can quickly start fire fighting. Must pay attention to the following points:  　　 1, the foam fire should be used side back to the fire, the water quickly, increase to the appropriate pressure (Dongfeng fire engines, for example, when using PQ8 gun pressure ≥0.686MP, use on-board gun pressure ≥0.785MP) , Open the pressure water cock, then open the bubble tank outlet ball valve, adjust the mixer to the proper position, aim at the center of the flame and spray the foam liquid.  　　 2. When using a foam gun to conduct close combat, fire engines should be protected as necessary based on the fire situation . The body can be covered with asbestos cloth and covered with water mist when needed.  　　 3. During the entire fire fighting process, the driver must stick to his position and pay constant attention to the immediate balance of the foam liquid of the vehicle, and add foam liquid in time. Once the foam liquid is used up and refilled, it will inevitably affect the entire fire fighting action.

Fire engine work major issues!
1, fire engines rushed to the scene in the driving process, we must ensure the safety of fast driving. The fire truck should choose to travel from the nearest fire engine access to the fire . When multiple trucks are dispatched, each workshop maintains a sufficient safety distance (50 to 80 meters is appropriate ) . After arriving at the fire scene, avoid multiple vehicles entering the same combat area at the same time to prevent the fire commanders from mobilizing the vehicles and putting them into fire fighting in time to delay the fighter.
